  1. From Nanovirus: But when cattle were first domesticated 9,000 years ago and people later started to consume their milk as well as their meat, natural selection would have favored anyone with a mutation that kept the lactase gene switched on.

    Well, I prefer Occams Razor. And natural selection also brought us cattle stealing – and some of us will always find a way to select the animal’s meat over it’s secretions.

    Perhaps the cow herders were just kin. “If you have an ethnic group which is rather a small population in size but happens to migrate over geographic distances then they might be more related to each other than the surrounding people”: The Amish evolutionary method.
